Release v1.2.0

UV Atlas Generator v1.2.0

Summary

This release promotes the current post-v1.1.1 work into a packaged Blender add-on release, with stronger validation, more flexible output naming, improved texture-source resolution, and faster image processing.

Added

• Atlas naming presets and custom templates using {object}, {atlas}, and {timestamp}.
• Validation and resolved-name feedback for atlas naming templates.
• Better user-facing validation for output paths and unsaved .blend files.

Changed

• Texture images are resolved from linked shader-graph nodes instead of simply using the first image-texture node found.
• Existing atlas datablocks can be reused correctly when overwrite behavior is selected.
• Region sampling and atlas image writes use NumPy and Blender bulk pixel APIs for substantially less Python-side pixel-loop overhead.
• Output naming and save-path behavior is more predictable for per-object and combined workflows.

Fixed

• Improved handling of materials whose relevant image texture is not the first texture node in the material.
• Better overwrite behavior for existing atlas images.
• Clearer failure messages when an output file cannot be resolved safely.
